IPC: G01L1/00
Filed: 1995-05-08
Abstract: PURPOSE: To combine changing function of resonance frequency with ultrasonic transducer function by applying an electromagnetic energy to an antenna coil forming a closed loop to generate a high frequency current, applying the high frequency current to an electrode to excited a piezoelectric oscillator, and observing the frequency of the ultrasonic energy by the excitation. CONSTITUTION: An electrode is provided on an oscillator, and an antenna coil 11 is connected to the electrode so as to form a closed loop. An electromagnetic energy is applied to a sensor 10 from the outside, whereby a high frequency current is generated in the coil 11. The generated electric signal is applied to the electrode to excite a piezoelectric oscillator 7, and the vibration of the oscillator 7 is leaked to a holding part or a vessel, and this ultrasonic energy is received by a microphone 3. Thus, an ultrasonic transducer and a temperature sensor are thus integrated together, allowing the downsizing of the device.

Abstract: PURPOSE: To simplify the constitution of a traveling position detector for vehicle without sacrifice of detection accuracy. CONSTITUTION: A traveling path is divided into a plurality of sections of an arbitrary length and a plate 4 having an arbitrarily variable length is arranged at every border. A sensor 3 for detecting the plate 4 and a rotary encoder 2 for generating a pulse in synchronism with the wheel are mounted on a vehicle 1. When the vehicle 1 travels and the sensor 3 passes over the plate 4, the pulses are counted and the count is held in a plate length butter 16. A number of section is then discriminated with reference to a table stored in a memory 19 and written in a section counter 12. The pulses generated when the vehicle is traveling through a section are also counted and held in a relative value buffer 15. Current position of the vehicle is determined based on the values of the counter 12 and a butter 15.

Abstract: PURPOSE: To keep the torque constant independently of perfmanent magnet rotor, by causing magnetism-sensitive elements to generate sine wave voltages and performing the pulse width modulation of the voltages and then applying the voltages to the armature coil.  
     CONSTITUTION: Hall elements H1, H2 are located near the permanet magnet rotor R and are supplied with driving currents of magnitudes corresponding to motor control signals to generate the sine wave voltages corresponding to the rotation of the rotor R. The voltages VH1, VH2 are pulse-width modulated by pulse width modulators W1, W2 and then applied to the armature coils W1, W2 through power amplifiers A1, A2. Therefore, a constant torque is caused independintly of the rotational angle of the rotor R. The magnitude of the torque is proportional to those of the currents supplied to the Hall elements H1, H2. Thus, the starting voltage can be made constant and low.

Filed: 1982-08-02
Abstract: PURPOSE:The enhance the reverse directional withstand voltage between the gate and drain by a method wherein the doping of two operating layers is performed independently. CONSTITUTION:On a semiconductor substrate 11, a shallow operating layer 16 is provided under a Schottky gate electrode 13, a deep operating layer 17 under the source electrode 14 and the clearance between the electrodes 13 and 14, and a deep operating electrode 18 under the dran electrode 15 and the clearance between the electrodes 13 and 15. Where, the resistance between the gate and source can be reduced sufficiently by performing doping by desired amount into the region of the operating layer 17 under the electrodes 13 and 14. Since the doping amount of the region of the operating layer 18 is determined independently of that of the region of the operating layer 17, the reduction of the resistance between the gate and drain is performed by doping within a limit wherein the reverse directional withstand voltage between the gate and drain is not damaged. Therefore, the reverse directional withstand voltage between the gate and drain is secured sufficiently, and simultaneously the resistance between the gate and source and that between the gate and drain are reduced, and then gm is enhanced.

Abstract: PURPOSE:To make it possible to simply measure the change of pressure by using one optical fiber. CONSTITUTION:Light emitted from a light source 1 is passed through a polarizer to be converted to linear polarized light and a lambda/2 plate 33 is rotated to align an incident polarization angle theta130 to a desired value (usually 45 deg.). In this case, the change of light output generated when external force F27 is added to a pressure sensitive part 37 with a length L is measured by an analyser 38 by a motor 39. A polarization degree E129 is shown by a formula I from the max. output¦EM¦<2> and the min. light receiving power¦Em¦<2> of light output. The linear polarization E129 obtained by projecting the polarization angle thetai30 to an angle other than 0 deg. or 90 deg. is represented by the vector sum of linear polarization components¦Ex¦<2>,¦Ey¦<2> in two axes X, Y crossing at right angles. When the phase difference of both of them is phi, the polarization degree P is shown by a formula II. Especially, when thetai is 45 deg., the polarization degree P is shown by a formula III. Therefore, the phase difference between polarization components in an optical fiber 35 is calculated.
